The clip features Clarke's Daenerys Targaryen who intrudes a "stupid contest" between Daario and Grey Worm, as the two men are trying to determine who will have the honor of riding by Dany's side at the front of her train of Unsullied. Dany, with just a few words, stops the contest which has kept her waiting.

During her "Tonight Show" appearance, Clarke also recalled her embarassing audience for "Thrones". "It was a lot of adrenaline, I was very nervous. There were lots of people from HBO there," she shared. "I did all of the scenes, and at the end, I said, 'Is there anything else I can do?' "

She said that showrunner David Benioff then "suggested I do a dance. So I did." She continued, "I did the funky chicken and morphed into a robot."

On the same night, her co-star Lena Headey paid a visit to "Late Night with Seth Meyers". She also debuted a new clip from the HBO series which highlights Cersei and Jaime Lannister's relationship following his return to King's Landing. Cersei is apparently angry that Jaime left her and wants him to apologize.

"Game of Thrones" season 4 premieres Sunday, April 6 at 9:00 P.M. on HBO.
